摘要 |
An RFID tag for use in a vehicle for use in an electronic toll collecting system. The tag is capable of transmitting data to a tag interrogator indicating the occupancy status of the vehicle. In an embodiment, the tag has a user input and a visual and audible tag status indicator. The user input is used to change the occupancy status of the tag, wherein the occupancy status is a portion of a message sent by radio frequency to the interrogator when the vehicle passes through a toll area. In an embodiment the tag has memory for storage of said tag status and the user input can be used to cause the tag to indicate a stored tag status. In a further embodiment, the tag reverts to a default status after a predetermined period of time.
